I/O Connector

6 I/O Connector

The DFM 36AX390-ML camera has a user GPIO I/O connector with the following pinout:

Pin Name Description

1 TRIGGER_IN_P Opto-decoupled trigger input, anode of IR-LED

2 TRIGGER_IN_N Opto-decoupled trigger input, cathode of IR-LED

3 GP_OUT General purpose output, referenced to GND

4 GND System ground

The trigger input is opto-decoupled. To drive the trigger input, a voltage must be applied

to pins 1 and 2. Note: pin 1 is the positive input; pin 2 is the negative input.

Important: The sensor of DFM 36AX390-ML does not support trigger mode.

Pin 3 is a general-purpose output pin that can be controlled via software. The pin can be

configured for TTL mode output or open drain output. LED2 indicates a possible

overcurrent.

I/O Connector

The recommended operating conditions of the user GPIO connector J3 are displayed in the

following tables. CAUTION: Functional operation beyond the recommended operating

conditions is not assumed.

Parameter Min Max

Trigger input voltage 3.15V 25.5V

Parameter Min Max

TTL-mode high voltage - 250mA @ 4V

TTL-mode low voltage - 250mA @ 0.05V

Parameter Min Max

Open-drain-mode voltage - 24V

Open-drain-mode current - 250mA

Please ensure that enough additional power is provided via the embedded system to

operate the connected devices at the user GPIO connector (J3).

I2C I/O Expander Configuration

7 I2C I/O Expander Configuration

Various I/O functionalities of the camera are controlled through a I2C I/O Expander.

The TCA6408A part has the 7-bit I2C-address 0x20. The table below depicts which signals

can be controlled through this expander:

I/O Pin Name Dir Description

P0 CAM_PWR O Enable CMOS sensor power supply

0: Sensor power disabled

1: Sensor power enabled

P1 RESET O CMOS sensor reset signal

0: Sensor is in reset state

1: Sensor is in operational state

P2 GPOUT_LEVEL O If GPOUT_SELECT = 0:

--->0: LED1 off

--->1: LED1 on

If GPOUT_SELECT = 1:

--->0: GPOUT is low/0 V

--->1: GPOUT is tri-stated or high/+5V (depends on

the setting of P3)

P3 GPOUT_PUSHPULL O GPOUT (PicoBlade) type selection

0: GPOUT is configured as open-drain-output

1: GPOUT is configured as TTL/push-pull-output

P4 GPOUT_SELECT O Function of GPOUT (PicoBlade) Pin

0: Not connected

1: GPOUT_LEVEL from serializer board

P6 RESERVED_6 O Reserved

P7 RESERVED_7 O Reserved

Sensor Clock Configuration

8 Sensor Clock Configuration

The sensor's input clock frequency can be configured via the clock generator Si5356A with

the I2C address 0x70 (7-bit). The input clock of Si5356A (CLKIN, pin 4) is connected to an

external crystal oscillator SG-210STF (25MHz). The generated frequency is output at CLKA0

(pin 25). The manufacturer's Clock Builder software tool can be used to generate the

required settings.

For more information about Si5356A, please refer to the datasheet:
